Exhibitions 2d, Marfa, Texas

For the past month I have been traveling throughout the USA and one of the most interesting destinations has been Marfa, Texas. This small West Texas town is a haven for Minimal and Conceptual Art. The gallery Exhibitions 2d has a lot of mathematically art work on display. Two artists represented by the gallery – Gloria Graham and John Robert Craft – were of particular interest.

Graham’s geometric paintings are based on the patterns found in the atomic structures of natural elements. “NaCl H2O Salt Water” features two crystal-like forms, both regular hexagons. The hexagon on the left is divided into three congruent rhumbi. The hexagon on the right is divided into six equilateral triangles. The addition of the three extra line segments to divide the rhumbi into triangles changes the hexagon dramatically. The symmetry goes from order 3 rotational symmetry to order 6. The perception of the possible 3-D form goes from a cube to a faceted diamond shape with 6 facets on top. Graham’s painting process for this work involves a layer of kaolin (a clay-like mineral) applied to canvas stretched over wood. The lines are drawn into this base. Through the drying process tiny cracks in the surface have formed. This gives the work a complex physicality that alludes to the natural environmental inspiration for the painting.

Craft’s cast iron sculptures are related to his life as a Texas rancher. They are solid and heavy, and have a rustic patina. Their rough physicality is juxtaposed to their intricate geometric forms. This work is made up of 60 basic elements stacked into a 4 by 5 by 3 rectangular solid. Each of the elements is a type of double cruciform with a pyramid set on each of the six ends. This forms negative spaces with 16-sided regular polygon shaped windows. Craft’s work presents complex 3-D repetitive tiling-like formations, while retaining the physical realities of the artist’s ranch experience.
